6 Things The Food and Beverage Industry Should Know About Quantifying Microbial Water Risk (QMRA)

If you’re in the food and beverage industry you may never have heard of Quantitative Microbial Risk Assessment (QMRA). In the municipal drinking water sector, however, it’s been used for years to analyze risks and provide a quantitative approach to guide the regulatory decision making process.

With the implementation of the Food Safety Modernization Act (FSMA), many QMRA concepts could be very useful for the food and beverage industry when evaluating which (if any) preventive controls may be required – especially as it relates to the many ways water is utilized in a plant’s processes.

Here are six key components of QMRA you need to know:
1. The type and concentration of microorganisms and pathogens in your incoming water source. What organisms are present? What are the typical concentrations and what is the range of extremes that are possible during a contamination event (water main break, cross contamination, lack of chlorine residual, etc.)?
2. The effectiveness of your existing treatment system as it relates specifically to the previous point. Are your water treatment barriers sufficient to handle the microbial concentration extremes associated with a contamination event?
3. The microbial and pathogen concentration remaining in the water post-treatment in your plant. Is all the water in the plant treated? Different water usages may be more critical than others. Consider the difference between water used as an ingredient versus water used in the initial stages of CIP. How much remaining microbial contamination is acceptable in these different water uses?
4. The type and concentration of microbial contaminants that would make it to the consumer based on consumption rates.
5. The infectious dose of the microorganisms and the potential rate of illness (annually). For example, <10 organisms is the infectious dose for E. coli O157:H7. Based on the previous points, and understanding the microbial concentration extremes associated with a contamination event, how frequently would the microbial concentration exceed the infectious dose for the various organisms identified in your process?
6. Annual health impact commonly expressed as Disability-Adjusted Life Year (DALY). In other words, DALY measures the health impact associated with contamination. (The World Health Organization has more information on how this is calculated: http://www.who.int/healthinfo/global_burden_disease/metrics_daly/en/).

For QMRA assessments in the municipal sector, calculating DALYs can help to prioritize and drive regulatory decisions. For the food and beverage industry, brand reputation and consumer perception are additional components that carry a significant financial impact which must be considered. A food recall could cost a company millions of dollars in addition to the negative health impact.

With regards to chemical contamination and/or microbial contamination, how much risk is acceptable? Obviously there is no universal answer, but the QMRA thought process can be an important starting point. The same is true for mitigating those risks.

For microbial contamination, UV is commonly used as a firewall for all incoming water into the plant, as it is generally a low-cost, low-maintenance option to get a multiple log reduction of critical microbial contaminants. For this reason, many plants utilize UV as their “Preventive Control” for FSMA compliance for their incoming source water.

Hanovia is Helping Al Rawabi Dairy in Dubai Keep its Milk Pure

To ensure the purity of its product, Al Rawabi Dairy in Dubai – the UAE’s largest – is using PureLine UV disinfection technology from Hanovia to disinfect water used in the milk production process. The UV system ensures the process is free from harmful bacteria such as E. Coli and Salmonella.

AlRawabi_Dubai_blog

According to Mr Ashraf, Al Rawabi’s Site Engineer, two of the major benefits of the Hanovia UV system are the low operational and maintenance costs compared to alternative disinfection systems, and the fact that UV disinfection is a completely clean technology which does not produce any disinfection by-products or aftertaste, unlike with chlorine disinfection.

Founded in 1989 with 500 Holstein and Friesian cattle, Al Rawabi now has 10,000 cows at its state of the art farm in Al Khawaneej. As well as distributing milk to over 9,000 outlets in the UAE, Al Rawabi also exports its products to Oman and Qatar. Animal welfare is a high priority for the dairy and all its animals are housed in special air conditioned units which protect them from the stifling summer heat.

The success of Hanovia’s PureLine UV technology in the United Arab Emirates is to be followed by the official Middle East launch of the new PureLine Ultraviolet Energy Optimised (UVEO) disinfection system at the Dubai Drink Technology Expo on May 16.

“Building on the strengths of the existing PureLine range, the PureLine UVEO takes advantage of an optimised hydraulic design to provide up to 60% improvement in the treatment capacity over conventional medium pressure UV systems, using just a single medium pressure UV lamp” says Hanovia’s Technical Director Mark Aston. “This means reduced running costs without compromising on bio-security. A single medium pressure UV lamp eliminates the need to install a bigger system with multiple lamps at higher flows, which saves on up front capital costs and lifetime spares costs.

“The system utilises a smart control system that reads the process water conditions using flow, transmittance and chlorine sensors to control the electronic ballast with ‘stepless’ power, automatically adjustable from 100% to 30%. This feature helps increase the life of the medium pressure lamp and provides further savings on power costs,” added Mark.

Commenting on the launch of the PureLine UVEO in the Middle East, Halim Mirza, Hanovia’s Middle Eastern & Africa Regional Manager’, said: “Ensuring product quality in the beverage production process, while also being price conscious, can be a difficult balancing act for local producers. They need to know that the disinfection technology they’re using is fit for purpose and will protect the product from pathogens such as Cryptosporidium or Salmonella. At the same time they need to balance the cost of that technology with the financial realities. The PureLine UVEO ticks both boxes, as it offers a very high level of biosecurity while also reducing operational costs. It achieves this by using less energy while still delivering effective water disinfection at required flows with a single medium pressure lamp.”

In addition to Al Rawabi, Hanovia has a growing list of impressive food and beverage reference sites in the United Arab Emirates and would be happy to discuss these applications with any interested parties. Please feel free to contact the company’s exclusive local distributor Water Engineering Technologies (WET) FZC, on telephone +971 6 557 8230 or e-mail sales@wet-fzc.com. WET is based in the Sharjah Airport International Zone.

Hanovia is launching its new PureLine Ultraviolet Energy Optimised (UVEO) disinfection system in the Middle East region at the Dubai Drink Technology Expo (DDTE) on May 16.

Designed for disinfecting process water in the food, beverage and brewing industries, the launch will be at booth C41, where Hanovia and its local distributor, Water Engineering Technology (WET) are exhibiting. The DDTE is being held at the Dubai Convention & Exhibition Centre between May 16-18.

Commenting on the launch Halim Mirza, Hanovia’s MEA Manager, said: “Ensuring product quality in the beverage production process, while also being price conscious, can be a difficult balancing act for producers. They need to know that the disinfection technology they’re using is fit for purpose and will protect the product from pathogens such as Cryptosporidium or bacteria like E.coli. At the same time they need to balance the cost of that technology with the financial realities.

“Hanovia’s PureLine UVEO range ticks both boxes, as it offers a very high level of biosecurity while also reducing operational costs. It achieves this by using less energy while still delivering effective water disinfection at required flows with a single medium pressure lamp. It provides effective treatment at the required flows using just one UV lamp, with up to 60% less power usage than conventional UV systems.

“With customers becoming more conscious about energy saving, the PureLine UVEO range lines up with green initiatives, providing a critical barrier against contamination by non-chemical means. Using the system at particular points in the water treatment process also allows customers to also prolong the life of other components, such as reverse osmosis (RO) filters, by eliminating the risk of downstream contamination. All in all, PureLine UVEO technology provides a more effective barrier and is optimised for the industry,” he added.

PureLine UVEO systems come in two ranges for water disinfection:
•    The ‘H’ Edition is designed specifically to meet the highly stringent food, beverage and brewing industry regulations. All wetted parts use food grade-approved materials, while a UV chamber with a high specification internal finish is available if required.
•    The ‘Standard’ edition, which provides required levels of disinfection and prevents downstream contamination before reverse osmosis (RO) filters and at the point of use.

“The Middle East region is a very important for Hanovia and we are strengthening our position here through partners such as WET, who we are sharing a booth with at the show. We have a growing list of reference sites in the region that attest to the effectiveness of our technology. We therefore encourage visitors to visit our booth and find out more about how our PureLine UVEO technology can help,” added Mr Mirza.

All Hanovia UVEO systems are provided with its patented ‘UVGuard’, which allows safe checking of the UV sensor (performance monitoring instrument) using a unique ‘eyelid shutter’ design, which protects the operator from exposure to UV light.

Hanovia Launches PureLine UVEO UV Systems Specially Optimised for Food and Beverage Applications

PureLineUVEO-blog

Hanovia’s PureLine Ultraviolet Energy Optimised (UVEO) medium pressure UV system uses up to 60% less power than conventional UV systems with just a single UV lamp. This delivers a guaranteed, consistent UV dose with reduced life cycle costs for the food, beverage and brewing industries.

Energy and cost reductions
Building on Hanovia’s 90 years’ experience in UV treatment, the PureLine UVEO takes advantage of an optimised hydraulic design to provide up to 60% improvement in the treatment capacity over conventional medium pressure UV systems. This means reduced running costs without compromising on bio-security.

A prime benefit is that treatment is performed with just a single medium pressure UV lamp, eliminating the need to install a bigger system with multiple lamps at higher flows. This saves on up front capital costs and lifetime spares costs.

The system utilises a smart control system that reads the process water conditions using flow, transmittance and chlorine sensors to control the electronic ballast with ‘stepless’ power, which can then automatically adjust the power from 100% to 30%. This feature helps increase the life of the medium pressure lamp and provides further savings on power costs.

Designed for the food and beverage industries
PureLine UVEO systems come in three ranges:

  • The ‘H’ Edition is designed specifically to meet the highly stringent food, beverage and brewing industry regulations. All wetted parts use food grade-approved materials, while a UV chamber with a high specification internal finish is available if required
  • The ‘Standard’ edition, which provides required levels of disinfection and prevents downstream contamination before reverse osmosis (RO) filters and at the point of use
  • The ‘Dechlor’ edition, based on either H or Standard chamber designs, which provides guaranteed levels of dechlorination coupled with strong disinfection to protect downstream processes such as Reverse Osmosis (RO) from premature aging and biofouling

Medium pressure UV lamps provide the highest possible UV output at the specific wavelengths required to destroy microorganisms. Medium pressure UV is especially effective against chlorine-resistant pathogens such as Cryptosporidium and Giardia. Reduced reliance on chlorine helps protect downstream contamination of filters early on in the water treatment process. Medium pressure UV is also very effective at removing ozone from process water, ensuring product quality before bottling.

UVEO technology provides the food, beverage and brewing industries with optimised UV systems in line with requirements. The PureLine UVEO’s chamber size, lamp power and control systems have been tested to ensure not only that high levels of process water disinfection are achieved, but also that green initiatives are met by lowering power consumption.

Safe, easy maintenance
The PureLine UVEO is provided with Hanovia’s patented ‘UVGuard’, which allows safe checking of the UV sensor (performance monitoring instrument) using a unique ‘eyelid shutter’ design, which protects the operator from exposure to UV light.

The UV system is available in a range of sizes and treatment capacities to meet typical process requirements. It is designed for easy installation into existing pipework and can be fitted with an internal auto-wiper which maintains UV output efficiency by regularly cleaning the quartz sleeve housing the UV lamp. Lamp replacement is also quick and easy, with the system designed to allow easy access, even in small plant rooms.

4th Generation Australian Winemaker uses Hanovia UV for Water Disinfection

BrownBrothers-blog

UV ensures bacterial count is kept to zero

To disinfect water in the winemaking process, Brown Brothers winery in Victoria, Australia has installed a Hanovia ultraviolet (UV) disinfection system. The system was installed by Fluidquip Australia, Hanovia’s local partner.

One of Australia’s leading family-owned wine companies, Brown Brothers has been making wine in Victoria for over 120 years. Over this time it has established a reputation as one of Australia’s most innovative wine producers.

Being a fourth generation family winery, it’s seen many changes in the Australian wine industry, yet the cornerstone of its success remains as a varietal wine specialist and winemaking innovator.

With this mantra in mind, the company selected Hanovia UV disinfection to treat the water needed for its wine-making process. UV delivers the most secure and environmentally friendly water disinfection available, with the UV-treated water used for bottle washing, process water, QC, laboratory water and just about anything else where clean and bio-secure water is required throughout the winery.

In 2009 Brown Brothers updated its existing UV water disinfection system to the latest Hanovia AF3 UV system. “Our Hanovia UV system has worked perfectly since we installed it in 2009. We routinely get a zero (bacterial) count after the UV. It wasn’t always that way – our old UV system would often return counts for bacteria of 40, 80 or sometimes even 100 CFU (Colony Forming Units),” says Steve Dows from Brown Brothers.

The Hanovia UV disinfection system safeguards Brown Brothers’ water from the risk of water-borne micro-organisms such as bacteria, viruses, yeasts and moulds, as well as harmful protozoa such as Cryptosporidium and Giardia, which are chlorine-resistant. It does this with no effect on the water’s pH, colour or taste, ensuring there is no impact on the quality, flavour or aroma of the wine, which is important when you are producing gold medal winning wines.

“Chlorine is a no-no anywhere in the wine making process as it can affect the taste of the wine,” adds Steve.

Brown Brothers use a deep bore as its water supply and positions the Hanovia UV disinfection system after 0.04 micron filters. UV disinfection has the advantage of using no chemicals and it introduces no disinfection by-products into the process. It is effective against all known microbes.

After being awarded several gold medals in the Royal Melbourne Wine Show in 2012, it’s clear that Brown Brothers continue to lay claim as one of Australia’s most iconic winemaking success stories.

Eco-UV project aims to bring new UV water disinfection technology to market

Funded by Horizon 2020, the EU’s biggest ever research and innovation programme, ECO-UV has as its central objective the “demonstration and characterisation of an innovative UV lamp and driving electronics technology for chemical-free water treatment and disinfection”.

EU-flag_blog

Led by UV industry leader Hanovia and partnered by three sector leading organisations: the premier research university Karlsruhe Institute of Technology (KIT) in Germany, DVGW, the German Gas and Waterworks Association’s Centre of Applied Research, and IVL, the Swedish Environmental Research Institute, the project brings together industry, academia and independent test and verification bodies.

The aim of Eco-UV is to develop ground-breaking UV technology for the treatment of industrial process water and other fluids with increased lamp life and greatly increased energy efficiency, providing a much lower carbon footprint and reduced environmental impact.

The project will prove the new UV lamp technology by demonstrating it in real applications, with full characterisation in terms of long-term stability, ageing effects and dose-response-relationship. The UV lamps will be integrated in Hanovia treatment systems and the performance of the whole UV system will be independently evaluated at DVGW and monitored for efficiency by IVL.

Testing protocols for different end-users applications will also be derived, which could act as the basis for a future standardised validation for industrial UV applications in the EU. A full Life Cycle evaluation of cost and environmental benefits in comparison to traditional UV technology will be assessed by IVL in order to ensure active uptake of the technology in the marketplace.

“This substantial award from the European Union represents a huge vote of confidence in the technical and economic ambition of Hanovia and our ability to deliver a new generation of highly efficient UV lamps,” comments Project Manager Jane Wallis of Hanovia. ”We are very excited to be part of this project, working with some of the world’s leading research, validation and environmental assessment organisations to bring to the market this new generation of UV disinfection technology and so help our clients around the world reduce their costs and carbon footprint.”
Eco-UV has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement number 641702.
